摘　　要：目的描述liliequist膜和环中脑膜的显微解剖特点及相互联系和临床意义。方法在手术显微镜下对10例尸头的liliequist膜和环中脑膜的特点及相互联系进行观察。结果 Liliequist膜由中脑叶、间脑叶组成,中脑叶的前端附着存在2种形式;中脑叶的外侧边和环中脑膜前端相续。环中脑膜由枕叶底面、小脑上表面、颞叶底面蛛网膜在幕切迹处汇合环绕中脑而成,分为前、中以及后部。Liliequist膜中脑叶的外侧边和环中脑膜前部相连。结论明确了liliequist膜组成,变异,外侧边和环中脑膜附着关系和临床意义。Objective To describe microsurgical anatomy characteristics and clinical significance of liliequist membrane and premesencephalic membranes and their relationship. Methods 10 formalin-fixed cadaveric head specimens were dissected to observe features of liliequist membrane and premesencephalic membranes, as well their anatomic relationship. Results The liliequist membrane was composed of diencephalic and mesencephlic membranes. Anterior attachment of mesencephlic membrane presented 2 styles. Lateral border of mesencephlic membrane attached to the anterior of premesencephalic membrane. The perimesencephalic membrane originated from the reflexion of the arachnoidal membrane covered the lower surface of the temporo-occipital lobe and the upper surface of the cerebellum, which could be divided into anterior, medial and posterior parts. Lateral border of mesencephlic part of liliequist membranes connected with the anterior of premesencephalic membrane. Conclusions The structure, variation, relationship and clinical significance of liliequist membranes and premesencephalic membranes are explored and analyzed in this study.
